Sport Bild correspondents Bianca Garloff and Ralf Bach report that Red Bull confirmed the meeting took place, at the behest of Alonso's management.

Photos of the meeting were even published.

Spaniard Alonso is under firm contract to Ferrari for 2014, meaning that the two-time world champion or Red Bull would have to buy out the deal if he really jumps ship to become Sebastian Vettel's new teammate.

"A decision is expected in the next seven days," read the Sport Bild report.
